Description of the invention (1) Technical field and industrial application of the present invention The present invention relates to the manufacture of glass fiber pellets. In particular, the present invention provides a device for manufacturing densified glass fiber weave pellets by combining multi-section chopped multi-fiber glass strands. Such pellets can provide a convenient form for the storage and disposal of chopped glass fibers used as a reinforcing material for composite structures. BACKGROUND OF THE INVENTION Chopped glass fiber is often used as a reinforcing material for thermoplastic articles. Typically, this fiber is produced by drawing molten glass through a crucible or perforated glass into fibers. 'Applying a sizing composition containing a slip agent, a coupling agent, and a film-forming binder resin to the fibers.' The fiber strands are in a desired length, and the sizing composition is dried. The chopped strand segment is then mixed with a polymer resin ' and the mixture is fed to a compression molding or injection molding machine where a glass fiber reinforced plastic article is to be formed. Typical chopped strands are mixed with thermoplastic polymer pellets. The mixture is fed to an extruder where the resin melts, the integrity of the glass fiber strands is destroyed, the fibers are dispersed throughout the molten resin, and the fibers / resin are dispersed to form pellets. These pellets are then fed to a molding machine and formed into a molded article with substantially uniform glass fibers dispersed throughout. Printed by the Consumers' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs—1 —-------- ^-W (Please read the note on the back before filling in the ears, but unfortunately this is a short-cut glass fiber manufactured by this method Typical bulky and poor flow. As a result, this kind of fiber is difficult to handle and cause problems in automated processing equipment. Β Trying to solve this problem is to compact chopped strands into denser rod-shaped tows or pellets to improve the flow of chopped strands. And the use of automated equipment to weigh and transport glass fibers for mixing with thermoplastic resin. This method is disclosed in US No. 4,840,755 'where the wet chopped strands are rolled, preferably paperless. The standard is applicable to Chinese national standards ( CNS) Α4 specification (210X297 mm 4 ------- 42β 6 04 Printed by the Ministry of Standards Bureau of the Central Bureau of Work and Consumer Cooperatives printed A7 B7 V. Description of the invention (2) Rolled on a swing carrier and rounded Raw silk and compacted into denser cylindrical pellets. Although this method and device can provide denser and more cylindrical pellets with better fluidity, it is still undesirably limited in some respects ... such as pellet size and The dimension content is usually limited by the fiber size and number of chopped strands, and the method is designed to prevent multiple chopped strands from sticking to form more pellets than the fibers that exist in a single chopped strand. As a result, in order to obtain For pellets with proper bulk density and sufficient diameter to length ratio to have good fluidity, the chopped strands usually have to be formed from more fibers. However, increasing the number of fibers formed and combined into a single strand results in undesirable formation. Work becomes complicated. In an attempt to overcome these shortcomings, U.S. Patent No. 5,578,535 discloses that glass fiber pellets are about 20 to 30% denser and about 5 to 15 times larger in diameter than the individual fiber precursors of their raw materials. These pellets The method of making granules is to hydrate the cut raw silk segments to a degree sufficient to prevent loose filaments but not enough to aggregate the raw silk segments into clusters' and the time for mixing the hydrated raw silk segments to be sufficient to form pellets. ^ Proper mixing methods include making fibers Methods of moving through each other, such as rolling, searching for 'mix, mix, stir, and blend. Although the disclosed pellets can be made by a variety of mixing methods, it has been found Many of these methods may be too ineffective for commercial use, or may not be properly controlled to produce a uniform pellet product, which provides the strength characteristics of the resulting composite article comparable to composite articles made from un-granulated chopped strand fiber For example, the use of modified disc granulators often results in the pellets staying in the mixer for too long. As a result, due to the abrasive nature of glass fiber pellets, the paper dimensions are subject to Chinese national standards (CMS > A4 specifications ( 2] 〇297 epidemic) (Please read the precautions on the back before filling this page) i Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 426604 A7 _____ B7_ V. Description of the invention (3) Pellets deteriorate. This The degradation of the seed pellets ultimately reduces the strength characteristics of molded articles made from the pellets. There is a need for an effective pellet forming method that can obtain a homogeneous glass fiber pellet product in a controlled manner, which can provide an unpelletized chopped strand fiber characteristic of a composite molded article. The present invention, which will be described briefly and hereinafter, can meet this need. SUMMARY OF THE INVENTION The object of the present invention is to provide an effective pellet forming method and device that can obtain substantially uniform glass fiber pellets having a shape and density that can provide good fluidity in a controlled manner. Another object is to produce pellets that can be used to make glass fiber reinforced composite articles, and there is no appreciable loss in strength properties when compared to comparative products made from ungranulated chopped strands. These objectives can be achieved by a method in which a glass fiber strand comprising a plurality of substantially continuous glass fibers is chopped into a desired length segment and hydrated to a water content sufficient to allow the strand segment to fuse into pellets during rolling. Subsequently, the raw silk segment receives the first rolling action to distribute the hydration solution substantially uniformly over the raw silk segment and combine the raw silk segments to form pellets. The pellets were then compacted by a second tumble to increase the pellet density thus obtained. The method of the present invention can excellently adopt a device comprising: (a) a device for cutting glass fiber strands to form chopped strand sections; (b) a device for conveying chopped strand sections to a first rolling device; (c) applying Device for hydrating solution to chopped strands; (d) The first rolling device is used to provide rolling action for chopped strands to disperse the hydration solution and align the chopped strands and fuse them into pellets; (e) Device for conveying pellets to the second tumbling device; (f) The second tumbling device, this paper size is applicable to China National Standard Mould (CNS) A4 specification (210X297 mm) 6 (Please read the precautions on the back before filling in (This page) ^ nr S.---l · · J--1 — l ^ i I--^^^ 1.:-I-I nn 1 -i 1繁 ^ 426604 A7 _B7_ V.

Although the water content of the raw silk section can be adjusted before it is introduced into the granulator, it is preferred that the glass fiber is hydrated to a water content suitable for forming pellets in the granulator. The water content of the fibers in the granulator is preferably from about 12% to about 16%, more preferably from about 13% to about 14%. If the water content is too low, the raw silk cannot be combined into pellets and the typical raw silk form is maintained. Conversely, if the water content is too high, the filaments tend to aggregate or cluster or form non-cylindrical pellets D which are too large in diameter and irregular. In addition, it is preferred that the hydrating fluid contains a binder or a second sizing composition. Thus, the 'hydration fluid contains appropriate ingredients such as those typically included in glass fiber sizing compositions such as film formers, wetting agents, antistatic agents, and additional coupling agents and lubricants. By applying this second sizing composition to the granulator, a 100% application efficiency can be obtained. In addition, 'sizing outside the fiber forming environment may contain materials that are not suitable for use in the forming process due to toxicity, cleanliness, odor, high cost, or shear sensitivity.

The industry can choose other suitable binder formulations or other useful ingredients. Indeed, the advantages of the present invention are almost all used in glass fiber forming technology The sizing formula can be used as a binder for spraying on the fibers in the rolling device according to the method of the present invention. In order to ensure the good coverage of the fiber filaments, it is preferred that the size be applied when the raw filaments enter the pelletizer. And start melting into pellets Pre-application ^ If the sizing is applied elsewhere on the granulator, the pellets tend to be formed before the chopped strands are completely coated with the sizing composition. As a result, the fiber-formed pellets cannot be fully coated with the sizing composition When such pellets are used to make fiber-reinforced plastic objects, 'uncoated fibers lacking an interfacial coating cannot obtain good strengthening characteristics, and the resulting object will have worse properties than optimal. The preferred granulator is equipped with a spray nozzle adjacent to the inlet of the raw silk section for spraying the sizing composition onto the raw silk section entering the pelletizer. The granulator used in the present invention can be any device that can roll the raw silk segments, so: (1) the raw silk segments become substantially uniformly coated with an aqueous binder / sizing composition 'and (2) a plurality of chopped raw filaments Segments are aligned and fused into pellets of the desired size. Such a tumbling device must have an average dwell time sufficient to ensure that the strands become substantially coated with a hydrating fluid and shaped pellets, but are not sufficient to cause the pellets to be damaged or deteriorated due to friction with each other through abrasion.

Description of the Invention (I3) The retention time is about 1 minute to about 10 minutes. More preferably, the residence time of the tumbling device is about 1 minute to about 3 minutes. The preferred granulator is a drum, as shown in Figure la. Drum 41. The granulator 41 accepts chopped strand segments 24, which can use a fiber forming crucible 11, a sizing device 13, a bunching shoe 14, and a chopping device. 20 生产。 20 preparation. In a preferred embodiment, the device is provided with a system for monitoring and / or adjusting various parameters, which can be automatically controlled via a control panel 70 such as an Allen Bradley PLC-5 / 40 PLC system. If necessary, the water content of the feed strand section 24 can be measured using a suitable device 71. The raw silk weighing device 72 may be provided and appropriately positioned, for example, in front of or behind the raw silk conveyor 30 or a combination of similar weighing devices may be used to monitor the weight of the pellets on the conveyor 31. The metering of the binder and water can be achieved by controlling the pumps 33 and 34. The drum 41 is suitable for containing a sprinkler head for applying a hydration solution to the raw silk section 24 entering the drum. A preferred external air mixing nozzle 47 is installed near the entrance of the drum for the mixed water-liquid adhesive composition, which can be passed through Masterflex Pump 33 is supplied by binder supply 35; additional water can be supplied by water supply 36 via Masterflex pump 34 to adjust the water content of chopped strands to the required level and apply the mixture to chopped strands in the drum segment. The adhesive composition and water are merged into a single fluid flow through the nozzle orifice, and then collide with the two air jets' at an interval of 180 degrees and an angle of 60 degrees with respect to the direction of the fluid flow. The air is supplied as clean dry air 52. The fine mist generated in this way is pushed onto the surface of the raw silk segment rolled in the drum. The rotation of the drum can cause the wet raw silk segments to roll over each other. At the same time, the surface tension generated by wet sizing or coating causes the raw silk segments to contact each other over a substantial part of their length to align with each other and melt into a cylindrical pellet.

Invention Description (14) tablets. Through this action, any fine particles or single fibers formed in the short-cut operation can be recombined and quickly mixed into the shaped pellets, and individual fine fibers are generally removed from the resulting pellets. It is preferred that the drum is slightly tilted so that the exit end of the pellets of the drum is lower than the entrance end to ensure that the pellets formed in the drum do not stay in the drum for too long. In a preferred embodiment, the rotating drum is inclined so that the angle between the rotating shaft and the horizontal angle (q) is about 1 degree to about 3 degrees. The inclination angle can be adjusted manually or automatically using an appropriate adjustment device 43a. The size of the pellets formed on the drum is mainly controlled by the water content of the raw silk segment. If the water content remains high, more strands of the raw silk are fused into one pellet, so the diameter of the pellet is larger. Conversely, 'if the water content is maintained at a lower concentration, fewer strand segments will fuse into one pellet and the pellet will have a smaller diameter. The pellets preferably formed by the method of the present invention have a diameter of about 20% to about 65% of their length. Such pellets are typically formed by combining about 70 strands to about 175 strands' each strand contains about 500 individual fibers to about 2000 individual fibers. The pellet size is also affected by the throughput of the drum. If the throughput of the drum is high, the residence time of the raw silk segment in the drum is short, and tend to form smaller pellets' because the fluid cannot be dispersed on the raw silk, and the raw silk cannot be fused to form pellets. However, the compacted pellets take less time because the shaped pellets have a shorter time in the drum. Although the compaction of several shaped pellets inevitably occurs in the granulator, it is typically not enough to increase the density of nine pellets to the extent that it provides the best fluidity. For this reason, after being formed in the granulator 41, the pellets are fed into a second tumbler or densifier 42 ', where the pellets are further compacted and densified. Available A7--^^^ 1 K _.

Description of the Invention (15) ~~~ " Compact the pellets without abrasion or other A low-impact rolling device that damages the pellets and degrades them. The preferred densifier has a gentler and less intense roll effect than a pelletizer to minimize the degradation of the pellets. In addition, the densifier preferably has an average residence time of less than about 5 minutes to ensure that the pellets are not deteriorated by abrasion. In addition, the average residence time in the densifier is from about 1 minute to about 2 minutes. The preferred densifier is a serrated tube suitable for rotation around its longitudinal axis (x) as shown in Figure lb. The zigzag pipe 42 is rotatably mounted on the frame 43 via a caster assembly 44 and is rotatably driven by a transmission motor 45. As the tube rotates, the pellets inside the tube are gently rolled through the tube while being pulled through the tube by gravity. As with the aforementioned drum, the serrated tube densifier is preferably tilted at a small angle to ensure that the pellets flow through the device without the residence time being too long. 39 is higher than tube outlet 49. Although pellet formation and densification can be performed in individual devices, such as individual drums 41 and rotary zigzag tubes 42 with conveyors 31 as shown in Figure ia, the method of the present invention can also be performed using other suitable devices . For example, pellet formation and densification can be performed in individual roll zones or roll sections within a single device. A preferred example of such a device is a "mine tooth" mixing machine 'available from Patterson Kelly on the market, examples of which are illustrated in Figures 2 and 40 of Figure 3. The mixer 40 includes a drum 41 connected at one end of the drum to a sawtooth-shaped pipe 42. The drum 41 and the pipe 42 are both rotatably mounted on the frames through a casting assembly 44 and are rotatably driven by a variable speed motor 45. The zigzag tube is attached to the drum in a radial direction far from the rotation center of the drum and is in fluid communication with the drum. Therefore, each time the drum rotates, the internal material of the drum flows into the pipe because the paper China National Standards (CNS) for Quick Use of Scales ^ Grid (210X 297 mm) (Please read the precautions on the back before filling out this page) 袈--426604 A7 £ 7 ___ 5. Attachment position of the invention description (16) Tie below the height of the drum material. The chopped strand segment 24 enters the pelletizing drum 41 through an inlet 46. The feed yarn segment is sprayed with a hydration solution via a nozzle 47 positioned adjacent to the inlet 46, preferably containing a binder, a film-forming agent, a lubricant ' antistatic agent, and a coupling agent. The granulating drum 41 rotates to roll the filament segments inside the drum to each other to distribute the hydration solution on the surface of the filament segment, and to align and fuse the filament segments into pellets 48. The pellets in the drum enter the zigzag pipe 42 through the opening 41a at the exit end of the drum and are further densified in the zigzag pipe 42. In a preferred embodiment, the 'drum 41 has an internal baffle, which can reduce the free fall distance of glass pellets and raw silk segments during the rotation of the drum. By reducing such a distance, the degradation of glass fibers and pellets due to impact and abrasion can be reduced, and the glass fiber reinforced molded articles made from the pellets can be provided with improved physical properties. Although the suitable baffle can take many forms, the particularly preferred configuration includes a schematic cylindrical baffle illustrated in the fourth figure and a curved plate baffle in the fifth figure. Such a baffle is preferably attached to the exit end wall of the drum 41 and protrudes inwardly therefrom—the section occupies a distance of about 10% to about 50% of the length of the drum. The gauge can be made of any material that can withstand the internal working conditions of the drum, such as stainless steel, and can be attached to the drum by bolts, screw grafts, or other appropriate means. When using fastening hardware such as bolts or screws, the edge of the baffle wall adjacent to the drum wall is preferably formed with a flange 83 to assist attachment. As shown in Fig. 4, it is preferable that the cylindrical baffle plate 80 is air-tight and the end is sealed to prevent the glass from entering. It is mounted on the exit end wall of the drum 41, so its central longitudinal axis approximately corresponds to the drum longitudinal axis. As used herein, "outlined cylindrical shape" includes real cylinders and pseudo-cylindrical pieces, which have flat, pushed or cut out parts or are in the paper size 剌 (CNS) A4 size (21GX297 mm) '---- 19- i ^ lm ^^^ 1 I--— II ^^^ 1 i ^^^ 1 m i /,-° (Read the precautions on the back before filling in this page) Printed by the Employees' Cooperative of the Central Standards and Soap Bureau of the Ministry of Economic Affairs Printed by the staff of the Central Bureau of Standards, Fanjing Department, A7, B7. V. Description of the invention (17) The length part has unequal radii. Preferably, the baffle has a diameter of about 20 to about 35 ° / the diameter of the drum.俾 Fully reduce free fall of pellets and reduce fiber degradation. Also, the diameter of the baffle is preferably increased along at least a part of the length of the baffle, so that the diameter of the inwardly protruding end of the baffle is smaller than that attached to the end of the drum β. Setting such a baffle can reduce the length of glass passing through the drum The diameter of the inwardly convex end of the preferred seeding plate is about 25 to about 60/0 of the diameter of the drum. In addition, the 'baffle' is preferably installed on the outlet end wall of the drum, so that it partially overlaps the drum outlet end 41a to reduce the return of pellets to the drum from the serrated tube densifier 42 when the unit rotates. This corresponds to shortening the average residence time of the pellets on the drum and helping to ensure that the pellets are not damaged or deteriorated due to excessive abrasion. A preferred baffle covers about 20 to about 30% of the opening area. As shown in Figure 4, the overlapped outlet portion of the baffle can be flattened, pushed, or modified in other ways to reduce the backflow of pellets while minimizing the obstacles from flowing into the serrated tube densifier. . As shown in Section 5 (b), the preferred curved baffle usually has a curved portion 84 and a straight portion 86 'and is mounted on the drum exit wall perpendicular to the wall and projects inwardly into the drum. The curved portion of the baffle preferably has a substantially constant radius, and the radius matches the exit radius ′ and the straight portion is preferably equal to the exit height α. As shown in FIG. 5, the baffle is preferably installed on the drum wall and the straight portion is adjacent to the exit. The rotating trailing edge of 41a, so when the outlet is located at the bottom of the rotation, the straight portion is oriented vertically, and the curved portion is bent higher than the outlet toward the center axis of the drum. By orienting the baffle in this direction, not only can the free fall distance of the pellets be reduced during the rotation of the drum, but it can also be used as a spoon or guide to assist the pellet flow through the outlet to enter the serrated tube densifier. Each increase in rotation can be used for this paper size to apply Chinese National Standard (CNS) Α4 specification (2! 〇X297 public ban) (Please read the precautions on the back before filling this page) Order ---- 20 426604 A7 B7__ 5 2. Description of the invention (18) The glass pellets flowing into the densifier are famous. This also helps to shorten the dwell time of the pellets on the drum and prevent excessive abrasion of the pellets. It was found that the average residence time of the pellets on the drum can be shortened from about 2 minutes and 35 seconds without a baffle to 1 minute and 40 seconds for a roughly cylindrical baffle and 1 minute and 20 seconds for a curved baffle. Also, 'the significant reduction in fiber degradation due to such baffles can be confirmed by the increase in physical properties of objects molded from the resulting pellets, including an average increase in tensile strength of about 2 to about 3% and an increase in flexural strength of about 1 to about 2 % And impact strength increase by about 4 to about 5% »Nine pellets are transported to the conveyor belt 50 and dried after densification, such as using a covered hopper oven with hot air 61 and cooling air 62 or any with a ventilation device 63 Appropriate drying equipment for drying. In order to shorten the drying time to an acceptable level for commercial mass production, it is preferred that the fibers be dried in a fluidized bed oven at an elevated temperature of about 250 ° F (121.lt) to about 560T (293.3 ° C). The densified pellets after drying can be sized and screened into a product container 66 or waste container 67 using a sieve 65 or other suitable device. By changing the throughput and water content of the glass strands, the glass fiber pellets can be about 13% to 60% denser and approximately 10 to 65 times more dense than the corresponding ungranulated glass strands. . For example, a chopped 4 mm (length) segment of a 2000 fiber strand composed of 14 micron (diameter) fibers typically has a bulk density of about 33 pounds per cubic foot (528_66 kg / m3) to 36 pounds per cubic foot (576.72 kg / cubic meter). After hydrating to a water content of about 13% to about 14% according to the method of the present invention and forming into densified pellets, the resulting dry pellets typically have a bulk density of about 40 pounds per cubic foot (640.8 kilograms per cubic meter) to about 55 pounds. / Cubic feet (881.1 kg / m3) ^ Due to the increased diameter-to-length ratio and increased density, this paper is sized to the Chinese National Standard (CNS) A4 (210X297 mm) .----- I ^^ 1 II 1 II -·· n > «· 1 {Read the notes on the back of the poem first and then fill out this page) Printed by the Central Laboratories of the Ministry of Economic Affairs and the Consumer Cooperatives 21 Α7 426 6 Ο 4 ___ Β7 _ V.
